SIREN AND ATTACHING MEANS THEREFOR.

Application filed larch 16, 1925. Serial No. 15,788.

To all whom it'may' concern: I

Be it known that we, Lns'rnn H. MILES and JAMES W. BAYLESS, citizens ofthe United States, residing at Los Angeles, in the county of Los Angelesand State of California, have invented a certain new and usefulImprovement in Sirens and Attaching Means Therefor, of which thefollowing is a full,

had to the accompanying drawings. I

This invention relates to sirens and attaching means therefor.

The general object of the invention is to provide an improved siren andoperating means wherein the artsare simply constructed and are hig lyeflicient.

A further object of the invention is to provide a fixed stator having arotor movable therein, wherein the parts are of improved construction.

Another object of the invention is to provide a siren together withattaching means wherein the attaching means includes a shaft offset withrespect to the axisof the rotor.

Another object of the invention is to pro vide a siren including a rotorand a stator together with a drivingpulley, all arranged in a novelmanner.

Another object of the invention is to pro-- vide an improved attachingmeans for a siren together with a novel operating means therefor.

Another object of the invention is to provide an improved bearingsupport for the rotor of a siren.

Other objects of the invention will be apparent from the followingdescription taken in connection with the accompanying drawings whereinFig. 1 is a central sectional view through a siren embodying thefeatures of our invention; Fig. 2 is an elevation showing a siren withthe cover plate removed;

Fig. 3 is a fragmentary top plan view show ing the offset supportinmember; 'Figs. 4 and 5 are fragmentary etails showing the openingscommunicationg with the cavities in the rotor; Fig. 6 is a plan view ofthe erefor; Fig. 7 is a side elevation showing the siren. and theoperating members; Fi 8- is an enlarged detail showing the portion ofthe operating member and Fig. 9 1s a sectional view showin a detail ofthe fastening member.

ferring to the drawing by reference characters, we have shown a sirenembodying the features of our invention at 10. This The cover is shownas provided with a horn 16 thereon and across the mouth of this horn wesecure awire gauze disc 17 The base member includes a boss'18 which isintegral therewith and adjacent the boss 18 but offset with respectthereto, is a holding lug or boss 19. The boss 18 is drilled out toprovide an aperture 21 which receives a drive shaft 22. This drive shaftis provided with a shoulder 23 upon which one member of a ball race 24is fitted while the other member of the ball race 24' is fitted in a rabbet 25 in the boss 18. In a similar manner a ball race 26 is arranged ina rabbet 27 and a dust cap 28 is secured over the ball race 26.

The rotor which is an important feature of our invention, is shown, at30; This rotor comprises a disc 31 having a peripheral flange 32 thereonand having a hub 33'arranged to fit over the shaft 22. The hub 33 isrecessed to save weight and the end there-- of engages the member oftheball race 24, which is in engagement with the shoulder 23. A nut 35serves to hold the parts in theposition described. The other end of the.41 Whlch serves to hold flexible discs 42 adjacent another bearingplate 43 which plate is held against movement by locking nuts 44. Thearrangement is such that the bearing assembly is looked upon the shaft22 thus pre venting vibration and at the same time, the

flexible discs 42 will engage a driving member and are mounted foradjustment'longi. tudinally along the shaft.

' The rotor 30 as reviously stated is ro vided with a peripheral flange32 whic is connected by means of ribs 45 with the hub 23. The ribs 45 inconjunction with the disc 31 provide a plurality of pockets forreceiving air and adjacent the outer end of each pocket a part of theflange 32 is removedto provide passageways 50 for air. The surface of.the flange defines the passageways '50.

which are preferably tapered as at 51. The onter flange 12 of the basemember 11 is also provided with slots .54 which correspond in peripheralspacing with the slots 50 previously described. The portions of theflanges orclam'pingmember extends. This clamp- 54 are beveled as at'55vin a manner similar to'the bevel 51 but in a direction reverse The ribs45, as will be noted by referring to Fig. 1, are cut away at 60toproduce a' pocket 61 in front of the horn 161 This. producesfa superiorsiren and this pocket feature we deem of considerable importance.

The boss 19'is provided with an aperture 62 through which a supportingshaftv 63 mg member is provided with a base 64 which, may have threadedbosses 65 thereon for securing it in place. s

The shaft '63 is provided with upper and lower sliding supporting meansshown as collars 66 and 67 whichare held in position by set screws 60.The lower supporting collar has; a ortion thereon engaging the body tomaintain the body in proper position. A spring 7 O is interposed betweenthe collar 67 and the upper portion of the boss 19 and the ends of thisspring are bent as at 71 to fit within recesses in the boss 19 and thecollar 67 respectively.

From the foregoing description it will be apparent that when the base 64has been .secured in position that. the set-screws 68 may be releasedand the boss 19 adjusted to proper position on the shaft 63. After thisadjustment has been shifted, the supporting means 66 and 67 will besecured in place by the-set screws 68 to hold the siren in operativeposition.-

' The under surfac'of the. boss 19 is provided with a set screw 75 whichis adapted to engage the lower set screw 68 to limit the swingingmovement of the base member with respect to the holding lug 19. Thespring 70 is so arranged on the shaft that its engagement with thecollar 67 and the boss 19 tends to turn the siren with the lower setscrew 68 in engagement with the set screw as shown in Fig. 3.

In order to drive thesiren it is preferably mounted with the flexiblediscs against the fly wheel of a gasoline engine.

The base member 11 is shown as provided with a bracket 81 which has auniversal connection 82 thereon. This'connection 82 has a link*83-secured thereto, which passes through a" pin 84, mounted formovement on a ell crank 85 shown in Figs. 8 and 9. The bell crank isadapted to be supported on a shaft 86 and may be rocked by means "of arod 87 which has a push button 88 thereon. The rod 87 preferably passesthrough the bottom of the body of the vehicle 89. I

The link .83 extends beyond the pin 84 for some distance and has aspring 90 surrounding it. This spring is retained by a washer 91 whichengages a cotter. pin 92.

A cotter pin 93 on the link '83 engages the pin'8'4.

A spring 94 is preferably connected through a bar 95 with the bracket 81so that it will aid in returning the disc 42 toxinoperative position.

.In Fig. 6 the device is shown in operative position. When'theoperator'wishes to sound. the siren he will push upon the*button,88flthus rocking the bell crank 95'and oansin a compression of thespring 90. This wi l exert'a pull upon the universal joint 82 and willturn the siren about the shaft 63 bringing the disc 42 in engagementwith the fly wheel-'80 to rotate the rotor.

Thearrangement including the spring 90 is of extreme importance asregardless of the quickness or amount of forceexerted on thebutton 88only a predetermined pull can beexerted on the rod, 8j3.thus preventingbreakage of parts. I

Referring again to Fig. 1 it will be noted I that the flange 32 of therotor is in close proximity to the flange of the base member or statorand also that the cover is arranged very close to the outer edge of theribs 30.

These parts are carefully machined to accurate dimensions and on accountof this accuracy, we are able tomake a device which is more simplethanothers with which we are familiar.
